“…The pattern of antibiotic resistance in both species resembled closely that found in clinical strains of A . hydrophila (Gilardi et al 1970) and contrasts with the pattern of more extensive resistance found in strains of A . liquefaciens isolated from fish in Japan (Aoki et al 1971).…”

Strains of Aeromonas have been isolated in high numbers from several activated sludge samples. Immediately after isolation, some displayed only weak or negative oxidase activity, produced both acid and gas from lactose, formed ‘metallic’colonies on Endo agar, and had IMViC reactions which were identical with those of Escherichia coli. Although such strains could have been readily confused with E. coli, further biochemical characterization showed that these belonged to the recently‐described A. sobria. Nitrogenase activity was absent in all strains of both A. hydrophila and A. sobria. Almost all strains of both taxa were resistant to ampicillin and penicillin V and 67% of both were bete‐hemolytic.

“…Carbon utilization and nitrate reduction by the strain ISO2-3 were evaluated and compared to the data reported previously for A. hydrophila, A. punctata, and A. caviae (Gilardi et al, 1970) ( Supplemental Table II). The carbon utilization pattern of the strain ISO2-3 was closer to one of A. hydrophila than those of A. punctata and A. caviae.…”

The microbial communities associated with electrodes in closed and open circuit microbial fuel cells (MFCs) fed with glucose were analyzed by 16S rRNA approach and compared. The comparison revealed that bacteria affiliated with the Aeromonas sp. within the Gammaproteobacteria constituted the major population in the closed circuit MFC (harvesting electricity) and considered to play important roles in current generation. We, therefore, attempted to isolate the dominant bacteria from the anode biofilm, successfully isolated a Fe (III)-reducing bacterium phylogenetically related to Aeromonas sp. and designated as strain ISO2-3. The isolated strain ISO2-3 could grow and concomitantly produce current (max. 0.24 A/m(2)) via oxidation of glucose or hydrogen with an electrode serving as the sole electron acceptor. The strain could ferment glucose, but generate less electrical current. Cyclic voltammetry supported the strain ISO2-3 was electrically active and likely to transfer electrons to the electrode though membrane-associated compounds (most likely c-type cytochrome). This mechanism requires intimate contact with the anode surface. Scanning electron microscopy revealed that the strain ISO2-3 developed multiplayer biofilms on the anode surface and also produced anchor-like filamentous appendages (most likely pili) that may promote long-range electron transport across the thick biofilm.
